Solution

The correct option is B 2
MetaphaseAnaphaseAnaphase-I
The complete disintegration of the nuclear membrane or envelope marks the start
of the second phase of mitosis and the chromosome spread through the cytoplasm of the cell, spindle fiber attaches and move it to the equator is metaphase.
Anaphase is characterized by the splitting of centromere and move towards pole so that the chromatids start separating.
Spindle fibers pull homologous chromosomes toward the opposite poles of the spindle by the process
called dysjunction and arrange on the equator. The number of chromosomes becomes half at this stage.
So the correct option is " 2"
